I've had friends, both male and female that I've lost touch with over the years for various reasons. One friend I got in touch with via email and she answered me within a couple hours saying she was so happy to hear from me. So yes, she did acknowledge me and promised she would call me later. That was probably 5 months ago but she never did call me and I was a little sad. I figure my drug/alcohol abuse was no secret and perhaps she didn't feel comfortable but that's okay. I can't say I didn't try right?
On the plus side, I had an old dear friend from Michigan call me back just a couple nights ago after I friend requested on facebook a couple times. I could see that she posts several times a day so there was a good chance she would get my visitor's message. She was laughing her ass off trying to figure out "who was this green-haired little elf girl with the unrecognizable name?" I hadn't spoken to her since 2004, she moved to Tennessee and got married. I'm still figuring out how facebook works. If you send someone a message who you're not friends with, it goes to a different box I guess?
So I found her by simply first and middle name (not a common name at all) She told me when she added me to her friend list, my messages and photos came in all at once. We are two old chicks and I was a little persistent so Yay, that was very cool! Sorry for rambling, I'm still giddy!

In your situation, it's probably better to try and email her but how would you get her email address? I think sending a friend request would be my first step. But if she rarely goes on there, you could be waiting a while. I would only contact her friends as a last resort and
only if you know them. Hope you eventually get in touch with her.
